"The version of JetBrains TeamCity installed on the remote host is prior to 2022.10.4, or prior to 2023.05. It is,
therefore, affected by multiple vulnerabilities:

  - In JetBrains TeamCity before 2023.05 bypass of permission checks allowing to perform admin actions was
    possible (CVE-2023-34218)

  - In JetBrains TeamCity before 2023.05 improper permission checks allowed users without appropriate
    permissions to edit Build Configuration settings via REST API (CVE-2023-34219)

  - In JetBrains TeamCity before 2023.05 stored XSS in the Commit Status Publisher window was possible
    (CVE-2023-34220)

  - In JetBrains TeamCity before 2023.05 a specific endpoint was vulnerable to brute force attacks
    (CVE-2023-34227)

  - In JetBrains TeamCity before 2023.05 stored XSS in GitLab Connection page was possible (CVE-2023-34229)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
